Lette/rs Patent No. 98,414, dated December 28, 1869.

IMPROVEMENT IN FEED-CUTTER.

The Schedule referred. to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, J. P. RANDOLPH, of Marietta, in the county of ashingtonh and State of Ohio, have invented certain Improvements inFeed-Cutters and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to` the annexeddrawings, making part of this specification, in which- Figure l is a longitudinal vertical'section;

Figure 2 isa perspective view.

Figure 3 is a sectional top view of a portion of the frame upon the front end of the cutter-box, showing part of the lever, the lug or hook thereon, and its guide on the frame.

Figure 4 is a top view of the plate for determining the length the feed is to be cut. v

The same letters are used in all the figures, -in the designation of identical parts.

My invention relates to a machine for cutting hay, straw, or other feed; and

My improvements consist in the construction, combination, and arrangement of certain parts pertaining to such a machine, as hereinafter more fully described.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, in the drawings, represents the box or trough, mounted upon legs A1, so as to raise it to a convenient height. The rear end is to be left open, and to its front end is to be attached the machinery for cutting the feed, which is fed forward by the opera-tor.

B represents a frame, of cast-iron or other suitable metal, secured to the front end of the box by means of ianges b lfb, extending underthe bottom and along its sides, as shown. Sockets Bl B* are formed on it for the reception of the tiont legs, which are secured therein by bolts or iniany other convenient manuel'. fllo strengthen the frame as well as to give to it a more ornamental appearance, its upper ends are united by an arched cross-bar, cast in one piece with it, or it may be cast separately and bolted to it. This arched har is suitably formed at a point, B2, to receive and have pivoted to it thc'upper end of a link, C3. Upon the opposite side, a bar or arm, B3, extends outward from the frame, bossed on its outer end, and there perforated to receive the bolt upon which the lever C is fulcrunied. Another arched bar or guide, B4, rises upward from this side of theframe, forming the segment of a circle, having thelever fulcrum as its centre. The sectional form of this guide is clearly shown in iig. 3,the reduced portion of which is to be held between the lever C and its hooks, and thus serves as aguide for the same. Theouterends of the arm BJ and guide B4 may be connected by au arched cross-bar, as shown, so as to strengthen them, and which also serves as a stopto the upward movement of -lthe lever.

'C represents a lever, which may have the form clearly shown in lig. 2. From the end where it is pivoted to the 'ba-r B3 of the frame, extends from it at an angle, and cast or formed in one piece with it, a short arm, O1, which is bifureated at its outer end to receive 011e end of the knife-frame to be pivoted to it, said arm and lever being again united together by a crossbar, c. A lng or hook, G2, is formed upon the inner side of the lever, which is to embrace the reduced portion of l Just beyond the the guide B4 along which it works. point where the hook is formed on it, the lever is bent outward, so -as to enable it, when pressed down, to clear the parts attached to the front of the frame.

C3 represents a link, the upper end of which is hinged to the frame B at a point, Bi, and has pivoted to its lower end the other end ofthe laufe-frame,y

which is thus suspended directly in front of the box between this link and the arm G1 of the lever. By,

thus arranging the knife, a drawing-stroke will beimparted to it by operating the lever.

D represents-the kuub-frame, which is to be recessed on itsinncr side to receive the knife Dl, which, when inserted in such recess, is to he iush with the Surface of the former.

E is a plate of metal, extending across the frontend of the box, and so arranged on the frame. B as to leave a small space between the same and such plate, such space gradually widening from top to bottom, conse quent upon the formation of the plate, itbeing provided with oblique langes upon its ends, by which i is inserted and held between the standards F andthe face of the frame. lts upper serrated edge is to be about flush with the .upper surface of the box bottom plate H, thus forming a support on the outer side of the knife for the hay to be cut. The knife, in outting, enters the space between this plate and the face of the iron frame..

F F represent two standards, the lower port-io ns of which are placed against thc flanges ot' the plate E, when allare secured to thc frame by screw-bolts. Thin washers, of leather or other material, are to be inserted between the standards and the plate, so that the fermier maybe brought closer to the frame B, in conjunction with which they serve as guides for the knife-frame, when required The edges of the standards facing each other are to be provided with grooves in their upper portions to receive the oblique flanges of another plate, Gr, the of'- ee of which is to determine the length the feed is to be out, such feed being pushed out ot' the4 end of the box, after 'each cut, until itabuts against this plate, (the construction of this plate is shown in lig. 4,) es

a. consequence of which the distance between it and the mouth ofthe box maybe lengthened or shortened by turning up one edge or the other of the seme.

H represents :t serrated plete of metal, which forms the lower front edge of the box, and extends back some distance upon the bottom thereof, to which it is Secured by bolts which pass through elongated holes in such bot-tom,-and in the flange b of the iron frame B, so that the f1'ont`.edge of such plete can be set accurately and. in close proximity to the knife, at all times. I

I4 is the compressing-board, pivoted in the box to its sides, as shown. It, serves to somewhat compress the feed before itis pushed out to ,be out by the knife. Lugs on the frame B prevent it from swinging back further than is desirable.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

1. The combination of the lever C, having a. hook, C2, formed upon one side, with the guide B of the frame B, substantiallyas and for the purpose set forth.

2. In combination with the above elements, the knife-frame D, knife Dl, and link C, substantially as and for the purpose setforth.
